Crop Protection Technologies for Sugarcane

I. Disease management technologies

Heat treatment to manage sugarcane diseases.

Aerated steam therapy (AST) has been developed at SBI during 1970s and is being used at different sugar factory areas in the country to manage grassy shoot phytoplasmas and ratoon stunting bacterium in the seed canes. Treatment of setts at 50 °C for 1 hour is recommended to inactivate the pathogens reside inside the setts. Seed canes in sugar factory areas are to be heat treated to eliminate / inactivate the pathogens and this address the problem of varietal degeneration in sugarcane due to grassy shoot and ratoon stunting.

Effective sett treatment device to deliver fungicides /bio-agents

Plant Pathology section has developed a portable, rapid sett treatment device for treating sugarcane planting material (setts/ bud chips) with fungicides or antagonistic microbes to protect from fungal diseases. In which the soaking time is reduced significantly and achieved more effective penetration of the chemicals into the sugarcane setts / buds due to reduced pressure created in the treatment chamber. Such treatment resulted in protection of young crop from primary sources of fungal inocula causing red rot, smut and wilt in sugarcane thereby reducing the chances of epidemic build up in the field.

Molecular diagnosis of sugarcane viral, phytoplasmal and fungal pathogens

Developed uniplex-, duplex- and multiplex-RT-PCR based diagnostics to detect sugarcane viruses. Specific primers were designed and PCR conditions were developed to simultaneously detect SCMV, SCSMV and SCYLV, the three important RNA viruses in tissue culture derived seedlings and mother plants. Similarly, PCR assays were developed to detect phytoplasmas causing grassy shoot disease and red rot pathogen. The molecular diagnostic assays were commercialized to tissue culture production units across the country to produce disease-free planting materials in sugarcane.

Yellow leaf disease (YLD) management through meristem culture and virus indexing

Yellow leaf disease (YLD) caused by Sugarcane yellow leaf virus (SCYLV) has become a serious threat to sugarcane cultivation in different regions. The epidemic nature of the disease reduced the varietal performance and became a major cause for varietal degeneration. The virus is not amenable for management through conventional heat therapy. To manage the disease, meristem culture combined with molecular diagnosis was developed. This approach has been successful in eliminating the pathogen in the planting material and varietal vigour has been restored under field conditions. Sugar factories have taken up healthy seed nursery programmes using disease-free seedlings supplied from SBI and developed YLD-free nurseries.

Management of red rot using Thiophanate methyl + Pseudomonas sp.

Red rot, major fungal disease in the country can be managed effectively by sett treatment with the fungicide thiophanate methyl either alone or in combination with PGPR Pseudomonas.

II. Pest Management technologies

1. White grub

a. Environmentally safe technology using EPF

The validity of the entomopathogenic fungus Beauveria brongniartii was established against the white grub Holotrichia serrata in a series of laboratory and pot culture studies at the Institute and field trials in a white grub endemic sugar factory area, M/s Bannari Amman Sugars, Santyamangalam, Tamil Nadu. A simple multiplication method using dilute molasses and formulation with pressmud and lignite was developed. The fungus has been found to persist in the soil for four to five years with a single application of the formulation. The product is being produced and marketed to its growers by M/s Bannari Amman Sugars.

b. EPN technology

Detailed studies made at the Institute have identified entomopathogenic nematodes (EPN) effective against white grub Holotrichia serrata. Most of the identified EPNs belonged to either species of Steinernema or Heterorhabditis. Bioefficacy of EPN was evaluated against different instars of white grubs and potential EPN was identified under laboratory, pot culture, microplot and field conditions. EPN technology for white grub management has been demonstrated at different endemic areas in Tamil Nadu and Karnataka. The EPNs are formulated for long storage and field applications.

2. Woolly aphid

An integrated protocol for effectively managing the wooly aphid problem in sugarcane has been developed & disseminated to factory areas as required

II. Mass multiplication technique for the woolly aphid predator Dipha aphidivora

A low cost laboratory protocol has been developed for the mass multiplication of the predator in trays using woolly aphid infested sugarcane leaf bits. At the end of 18 days, about 350-400 cocoons can be recovered from a single tray. The output from a single tray would be sufficient to release inoculatively in one acre of woolly aphid infested crop.

III. Insecticide Residue Detection Protocols

Simple, easy to adopt sensitive protocols for the determination of insecticides residues in sugarcane juice and its downstream commercial products have been developed with respect to some of the commonly recommended insecticides in sugarcane crop system.
